Abstract
This study assessed (a) whether three girls with multiple disabilities and minimal motor behaviour could acquire pairs of responses taught through micro-switch-based programmes and (b) how the girls would eventually choose between those responses. In relation to the choice issue, a response-choice analysis was conducted to find out whether possible differences in performance rates for the two responses were due to the stimuli linked to them and/or to potential response preferences. Results indicated that all three girls succeeded in the acquisition of the two responses programmed for them and showed clear response choices. The choices seemed to be largely motivated by the stimuli linked to the responses. Implications of these findings were discussed, including the need to assess their generality and extend the scope of the work in this area.
